UM2 - from original gear to MK7 - which settings?

[oceanblue72 5]

Hello,

i've modded my UM2 with a Reprap Bulldog feeder (link to my post in the german section), original UM2 stepper motor.

For that i've changed the original gear with a MK7 gear.

The MK7 gear ist bigger than the original:

original scope: 25,13mm

MK7 scope: 34,55mm

So with the bigger scope there is more material transportation. Which settings must be changed - flow, filament diameter, e stepping?

For now i've changed the material flow on the UM2 to 95%, which seems to be quite good.

Thanks

Marcus
